To all whom. t may concern.'

Be it known that I, CHARLES C. HANSEN, J

a citizen of the United States, and a resident of Easton, county of Northampton, and

State of Pennsylvania, have invented a certain Shoveling and Loading Machine, of which the following is a specication accompanied by drawings.

This invention relates to shoveling and loading machines, and the objects of the inventionare to enable a scoo or shovel to be actuated for di ging an also to be elevated and lowered y one pair or set of pressure fluid c linders mounted on a carriage', and enab e the scoop to be dumped and also adjusted in the course of digging or dumping by another independently controlled pair or set of cylinders.

The resultant of forcesl actuating the scoop by the two sets of independently controlled cylinders, produces a exibility of action and control which enables more work to be accomplished in a given timethan heretofore and simulates more nearly on a large scale, the movements eiected on a small scale by the arms of a manual laborer in shoveling earth or rock with a hand shovel.

The invention is shown in one of its preferred forms in the accompanying drawings inwhich,

Figure l is a side elevation partly in longitudinal section of the shoveling and loading machine, certain parts'of the frame and the conveyor not essential to the disclosure of the invention being 'broken away or omitted for clearness of illustration.

Figures 2 to 5 inclusive are detail diagrammatic views illustrating a complete cycle of movement of the scoop or shovel from initial digging position to elevated dumping position and return.

Referring to the drawings theecarriage or frame A of the machine is shown in this instance provided with skids B adapted to slide along the rails C although, if desired, wheels (notv shown) could be provided for the carriage or frame A.

The material D is shoveled upwardly and rearwardly by the scoop orshovel E and dumped backwardly into any suitable form of conveyor F which delivers the 'material upwardly into the car G. The f rame or trough Vonl `of the conveyor is indicated, 1t being un erstood that suitable driving chains H are adapted to be actuated by a motor which may be a pressure fluid motor shown in this instance mounted on the s1de olf the conveyor trough and having the operating shaft K.

The digging, elevating and lowering movements of the scoop E are effected by a pair of c linders L mounted side b side and eX- ten ing'longitudinally on the rame A. The dumping ofthe scoop and also various ad- Justments of the scoop) both in digging, rais- 1ng, lowering and dumping are efected and controlled by dumping and scoop adjustment cylinders O of which there are two pivotally mounted preferably at their rearward ends on the pivots P conveniently located on the frame above the digging, elevating, and lowering cylinders L. Certain combinations of ad]ustments of the scoop 'E may also be effected by simultaneous control of the independent controlling valves for the two sets of cylinders L and O as willhereinafter appear.

The scoop E 1s provided with a front digging element Q indicated inthe' form of dlgging teeth and the rearward end R of the scoop E is open as indicated so that the material filling the scoop is dumped rearwardly into the conveyor F. A shield S is preferably provided at the lower end of the conveyor' F over which the material is dumped.

At the forward end of the frame A, guiding and supporting links U are pivoted at the points W to the rearward end of the scoop E. These links U support the scoop and rock on their pivots V as the scoop is manipulated.

rlhe pistons of the digging cylinders have their piston rods Y connected to cross heads Z movable on cross head guides a on the frame A and these cross heads are connected byh links b to the heel c of the scoop E. The pistons d of the dumping cylinders O .have their connecting rods e pivotally connected preferably at the points W to the rearward end of the scoop.

The two pairs of cylindersL and O have independent controlling means of any suitcylinders. Pressure duid as for instance compressed air or steam is supplied to the pipe connection p which branches and leads to each of the valve casings g and and from the valve casings pipes g and r lead respectively to the ends of the two sets of cylinders L and O. The valve casings g and k are provided with the usual vents 3 s0 that manipulation of the valves controls the movements of the pistons X and d..

In the operation of t e apparatus let it be assumed that the digging.. pistons X are retracted while the dum ing istons d are at the forward ends of their cylinders as indicated diagrammatically in Figure 2, in which case the scoop E will be in its lowermost position in readiness for the digging stroke. As the digging pistons X are advanced in the cylinders L to the position indicated in Figure 3 while the dumping pistons d are maintained in the forward positions, the scoop E is thrust forward and lled with material and carried upwardly to the `position indicated inY Figure 3. The cylinders O and pistons d form abutments for the rearward end of the scoop which swings about the pivots W as the diggingl element Q of the scoop passes upwar y t rough the arc t indicated by dot and dash lines, finally arriving at the point fu..

At this point the pistons X are held stationary at the forward ends of their cylinders L and the pistons di of the dumping cylinders O are retracted to the position indicated in Figure 4, and also in Fi ure 1, 1n which case the material is dumpe over the rearward end of nthe scoop into the conveyor .As shown in`Figure V5 by retracting the pistons X of the cylinders L the diggin element Q, of the scoop is lowered throug the ,arc ai, indicated in dotted lines, to the point fw, and then b actuating the pistons d of the cylinders O orwardly the digging element Q, of the scoop is further lowered through the arc m to the starting position indicated in Figure 2.

During these digging, raising, dumping and lowering movements of the scoop, the supporting links U swing about their pivotal points V so that the pivotal supporting points W of the scoop change position as re uired for the various operations.

ne of the im ortant advantages of this construction resi es in the fact that by manipulating the valves f and j during any of the movements described, the scoo may be adjusted so that it does not pass t rough a fixed cycle of operations, because the pivotal supporting point W of the scoop may be altered by actuating the pistons d, and at the same time the diggin pistons X may be moved backward and orward to obtain additional thrust on the scoop and release it from boulders or lift the digging element of the scoop over the boulders or other obstructions.
